VOC filters and cassettes are gas filters filled with chemical volatile organic compound adsorbents designed for easy handling and replacement. They are available in various models to cater to different air treatment applications, considering factors such as available space, air-flow volumes, type and concentration of contaminants, and desired medical life.

Activated charcoal or carbon filters are highly porous and effectively filter VOCs in commercial, residential, and industrial settings. They reduce harmful or irritating compounds present in indoor air, such as formaldehyde, benzene, and polyurethanes. The filters use a different filtration mechanism than particulate matter air filters and are easy to install and maintain for optimal product transport environments. These filters offer high performance and efficiency and provide air filtration, purification, and corrosion protection for goods and the environment.

Chemical Media

Alphablend 8A This is our standard chemical media for this filter and consists of a blend of virgin activated carbon and Alphasorb 8, capable to remove a broad spectrum of malodorous and toxic compounds such as hydrogen sulfide, dimethyl sulfide, mercaptans, nitric oxide, formaldehyde, and VOC’s among others.
Alphasorb 8 Potassium permanganate impregnated activated alumina spheres for the removal of oxidative compounds such as formaldehyde, ethylene, and mercaptans.
Alphasorb 15 Caustic impregnated activated alumina spheres for the removal of chlorine and acid gases such as H2S.
Alphasorb 60 Virgin activated carbon for general odours & VOC’s adsorption.
Alphacarb N Impregnated activated carbon for the removal of ammonia and amino.
Alphacarb HG Impregnated activated carbon for mercury vapour’s removal.

Particulate Filters

Includes pre-filters, high-efficiency filters, absolute filters, and electrical filters.


The Chemifilter is a standard frame gas filter that incorporates chemical media, widely used in industrial air treatment units. It is suitable for deodorizing and purifying the air in various applications such as public buildings, hospitals, laboratory hoods, museums and archives, white/clean rooms, ships, hotels, restaurants, and more.


The VOC chemical filtration modules are housed in durable plastic containers containing filtration pellets that deliver superior performance with minimal pressure drop. These modules are engineered to minimise maintenance and lower operating costs. Available in four sizes to meet diverse applications, they are designed for effortless handling and replacement. These modules can be pre-filled from our production facilities or refilled using removable caps. The appropriate module for users would depend on the system design.
